Shared APPL_TOP

Experts:
I was told we have shared APPL_TOP. This is 11.5.10.2 on unix, 10g db, two apps tier. My question is: when I migrate Concurrent Program, I only exe on one tier or both?
Thank you for your help.

EBS 12.1.3 RAC to RAC Cloning with Shared Appl_Top

BismillahirRehmanirRahim
Dear All,
I need to Clone our Production EBS Environment from RAC to RAC with Shared APPL_TOP and Multi Tier Appl Tiers.
We have EBS 12.1.3 Environment with 2 Appl Tier Nodes with Shared Appl_Top & EBS DB is on 11gR2 RAC 11..2.0.4.
I am following Doc IDs 406982.1 & 559518.1.
But its not clear which directories need to be copy and restore for Shared Appl top on each Node.
Also what Steps will need to be executed on Each Nodes and
What Steps need to be executed only on one Node.
Appreciate your feedback.
P.S.
Kindly share if anyone have Step by Step Doc for RAC to RAC EBS Cloning.

Hi Hussein,
thanks for the reply.
+The path is different (first path is db while the second one is apps), so copy the file from the source instance to $COMMON_TOP/clone/context/apps directory on the target instance and try then -- Troubleshooting RapidClone issues with Oracle Applications R12 [ID 603104.1]+
What I meant to say that CTXORIG.xml already exists in the correct directory in the target system:
$COMMON_TOP/clone/context/apps
Anyways, I recopied the file from source to the target system $COMMON_TOP/clone/context/apps, but still the same problem. I'll continue reading "Troubleshooting RapidClone issues with Oracle Applications R12 [ID 603104.1]".
I noticed below when running "perl adcfgclone.pl appsTier" with perl debug mode:
Cwd::_backtick_pwd(<10.1.3 ORACLE_HOME>/perl/lib/5.8.3/aix-thread-multi/Cwd.pm:204):

Query regarding converting application tier (concurrent and reports) into shared APPL_TOP

Hi,
Our E-business suite production server has four nodes configuration. 1. Application Nodes: APP1 , APP2 (Web and forms services are running on these two nodes) 2. Database Nodes: DB1, DB2 (DB-SRV - common name) (SAN storage with Active/Passive OS cluster configuration) Also the concurrent and reports services are running here.
Currently, the APP1 and APP2 application files are configured in shared APPL_TOP. It is not enabled for concurrent and reports services which is running along with database. I already checked the metalink doc id for the same.
I'm expecting your suggestion that we should take care while enabling the shared APPL_TOP for concurrent node+reports.
It would be also great, if any one give rough outline plan for the same.
Thanks in advance.
Regards,
Senthil

Hi,
Below is my plan to add the conc admin and reports server to the shared appl_top.
1. Run adpreclone.pl appsTier on the conc admin node. i.e. run adpreclone in node DB-SRV
2. Verify and enable context variable s_isAdConc, s_isAdConcDev context variables.
3. Mount the node-App1 application file system to node DB-SRV.
4. Copy the existing .rdf files(located in DB-SRV) to the shared appl_top.
5. Then run autoconfig on DB-SRV.
Can anyone review and let me know, if something is wrong here or need to be modified?
Regards, Senthil

Diff between shared appl_top and multinode

Dear all,
Can anyone tell me know what is the difference among shared appl_top ,shared application tier file system and a multinode installed system..
Advance Thanks
Kai

1) Is the above shared application tier or shared appl_topNeither Shared APPL_TOP nor Shared Application File System.
2) If so, if it shared application tier, how can we say appl_top and
comn_top ,Application Tech Stack are mounted ....we are only sharing the service.You only share the storage. So, instead of having multiple copies of APPL_TOP/COMMON_TOP, you just have one copy shared between the two nodes. This means, if you do any changes to APPL_TOP/COMMON_TOP from Server 1, then you can see the change on Server 2.
> 3) if it is not a shared appl_top, what change has to
be made in the above scenario to make it shared appl_top.. To make it:
Shared APPL_TOP --> You need to include COMMON_TOP (in addition to APPL_TOP).
Shared Application File System --> You need to include COMMON_TOP, 8.0.6 ORACLE_HOME, iAS ORACLE_HOME (in addition to APPL_TOP).
4) How it is said that the appl_top,comn_top and ora
are shared..we are only distributing the services.. Again, shared means the same storage can be accessed by both nodes. Any changes made in the shared storage are immediately visible on all nodes.
In traditional multi-node installation, you have more than once copy on APPL_TOP/COMMON_TOP, so whenever you need to apply an application patch, you have to run it on each node which has APPL_TOP. In the Shared APPL_TOP configuration, you only need to apply the patch once, since the change will be visible immediately to the other node.
No matter you have Shared APPL_TOP or Shared Application File System or traditional multi-node installation, by the end you will be running CM on Server 1, and Forms/Web on Server 2.
Hope it is clear now :)

In SHARED APPL_TOP

in shared appl_top where will be the IAS environment file
whether it will present in all machines r in single machine only

for upgrading developer 6i with oracle applications they ask to do
Set ORACLE_HOME to <iAS_HOME>/6iserver
Prepend <iAS_HOME>/6iserver/bin to the beginning of PATH
Prepend <iAS_HOME>/6iserver/lib to the beginning of LD_LIBRARY_PATH
Do get confused with what is written in the patch README file. For upgrading Developer, you need to patch 8.0.6 ORACLE_HOME (NOT iAS ORACLE_HOME).
where i have to do this
im having shared appl_top systems
i saw in all machines no env file for iasIf you have Shared APPL_TOP, then 8.0.6 ORACLE_HOME (i.e. Developer 6i HOME) should be installed on each application tier. You have to install the patch on each node which has 8.0.6 ORACLE_HOME.

PCP in non-shared appl_top application tier

Hi Guru's,
I wanted to know few information about non-shared appl_top in application tier.
Can we implement PCP(Parallel Concurrent Processin) in non-shared appl_top application tier.?
What should be design of oracle application node in case of non-shared appl_top environment with HA(high availability)?

Rajkumar Agarwal

Hi Hussien,
I am in process for load balancer configuration . I am still in doubt that it will resolve my problem that's why i am trying to explain my problem in detail .
I have configured shared appl top in active/active mode between 2 node. After configuration I tried to access apps login page from both the nodes separately like below
http://node1.domain:8000
http://node2.domain:8000
node1 and node 2 are my primary and secondary node.
If I access primary node url its working fine and there is not issue with that .When i tried to access secondary node, the login page url getting redirect to primary node only and login page appears.Which means application is accessible from primary node only and whenever I hit node2 its redirecting request to primary node which should not be the case in active/active configuration.
When I stopped services from primary node and tried to login from node2 ,I am getting "page cannot be displayed"
I ran autoconfig on node2 and its start working fine but primary node now converted into secondary node and redirecting login page to node2.
Now as a solution of above problem you asked me to configure load balancing , below are my questions
1. Is there any problem in configuration of shared appl top or its a default behavior of application?.
2. After configuration of load balancing , would i be able to access login page from both the nodes?
3. Incase my primary node goes down, will my application will be accessible from secondary node ?
Kindly clarify above queries in detail.
Thanks in advance,
Regards,
Raj

How to find out whether it is shared Appl_top?

How to find out whether it is shared Appl_top?

Hi,
In a Shared APPL_TOP installation, the APPL_TOP and the COMMON_TOP file systems are installed on a shared disk resource mounted to each node in the system. These nodes can be used to provide standard application tier services, such as Forms, Web, and Concurrent processing. Any changes made in the shared APPL_TOP file system are immediately visible on all nodes.
Note that each node continues to have a separate Applications techstack installation.
I have given the concept of shared Appl_TOP , so that you can understand "How to find out whether it is shared Apll_TOP".
Hope, this will help you.

Need guidance on how to attach forms home in shared APPL_TOP

Hi
I am on 12.1.3 and need to register the forms 10.1.2 home with the installer. The problem is that it does not seems to be that straightforward when it is a shared appl_top(2node), which was cloned from a single node config.
What is the correct way to register the oracle home on both nodes, syntax-wise?
Kind regards

Shared APPL_TOP config mentioned in context file??

Hi,
Is Shared APPL_TOP config mentioned in context file?? If yes, then what is the entry for it in context file ?

I am searching for this keyword
grep -i "APPL_TOP oa_var" $CONTEXT_FILE
In all tiers the $APPL_TOP location mentioned in $CONTEXT_FILE is same.
Is this the method to check the shared appl_top ??

Hi,
on one node i have created one file (a.txt) under appl_top.There after on another node (rm a.txt) with that i came to know it is shared.
and also in configuration file the values are as follow
